How to disassemble for troubleshooting?

A friend has one that will not turn off - as soon as it's plugged in, the pump runs continuously. I feel pretty confident about troubleshooting the electrical parts, but we haven't figured out how to get the top cover off! The two big conical plastic inserts on either side of the portafill seem like the key, but having taken them out I can't see what to do next.

    I'm on my second Breville with the same problem. You plug it in and the pump starts without pressing the power button. The first Breville I had was kindly taken back by the manufacturer and now I have to do it again. I'm wondering whats going on here. It appears to be a mellon of a product.

    my machine was dead. replacing the #6 zener diode as mentioned in this post fixed it:

    "The zener diode, labeled ZD6 (1N4749A) on the circuit board was burnt."

I can't get the clear plastic cover off the circuit board... Seems there might be another screw I am missing. Also, can't get the gray plastic cover off the left hand side, near where the power cord goes into the machine

I just tried disassembling it. With the machine facing you, the
circuit board is on the left panel. You just need to unscrew and take off the grey plastic on the left, and you will see the electric
cord and a circuit board inside a clear plastic case.
There are 2 grey plastic conical inserts (they are recessed into
the machine) one on each side, next to where the water drips into
the coffee filter, use a long philip head screw driver to loosen the
screws until the inserts drop. These two inserts are holding the top lid in place. Now with the machine facing away from you,
push the top lid forward, it should come right off.

You can now take the circuit board clear case out. Carefully
and gently pull the wires out with a piler, some are difficult to

I probed around different components. The zener diode, labeled
ZD6 (1N4749A) on the circuit board was burnt. When not burnt, you should
read about 0.46V when you test it with a multimeter. This diode
is next to 2 blue electrolytic capacitor. This zener diode is
easy to find, it is like 5 cents, definitely not $40.

After taking off the two big conical inserts, you have to slide very strongly the top from the back to the front. It will pop out and then you will be able to remove the top.

My 2001vw passat some times won't start unless i use starting fluid.I have changed air filter and spark plugs. When i hook it up no codes come up

Troubleshooting steps:
  1. When you first turn the key on, listen for the sound of the FUEL PUMP (humming sound). If you just turn the key on but don't turn it to START, the fuel pump should run for no more than 3-5 seconds. If it does, continue troubleshooting;
  2. If the FUEL PUMP runs longer than 3-5 seconds, check for fuel leaks.
  3. Test pressure at the fuel rail. If pressure is erratic or too high at idle, replace the fuel pressure regulator;
  4. If fuel pressure is too low at idle, replace the fuel filter. Still too low? Replace the fuel pump and fuel pickup strainer.

Why does it start on ether but will not run without it?

Because it is not getting any fuel! as soon as the ether burns up if no fuel then it quits. check all fuses and relay for fuel pump. to check fuel pump to see if its running. have someone turn the key to start, while somebody is under car at fuel tank. hold hand on tank, if it works you will feel the vibration from pump. most relays for fuel pump are in under hood fuse box. a fuel pump if good, will only run a few seconds to build up pressure in line. when engine starts it runs continuously. so you may have to turn key on a few times. Good-Day!

I am a fifteen year old girl but I act like a tomboy. So many of my class friends make fun of me and especially some pretty girls in my school bully me about it. I wish they would respect my feelings. It...

Hi Sylvia,

Sorry to hear you are being bullied, I know it can be pretty horrible but try not let them get to you, everyone is different and individual and that is what makes us all so special. Bullies are unhappy or frustrated or even angry with themselves and try to gain control over your feelings so you will feel as bad as they do. When they make fun of you try to walk away or ignore them or if you are confident enough calmly tell them you are not interested in what they have to say, if you have to practice your calm responses then do so out loud into a mirror until you feel confident enough. If you keep repeating these actions they will soon see you are not a suitable target and will start leaving you alone. If they are physically hurting you always make sure you protect yourself.

You really should confide in someone about this and talk your worries over with them whenever you need to, preferably an adult like your parents or maybe an aunt, a teacher or perhaps a good friend. They might be able to help stop the bullying, make sure you report every incident to whoever you choose to talk to about it.

To help with the worry and stress take up some sort of exercise it can really help, maybe go running or even just go to your room and punch at the mattress for a bit. Don't let thoughts of what they have said run around in your head afterwards either, try pushing those things out and think about things you really like. Make a list of positive things about your yourself and when you feel down because of the bullies read your list to remind yourself of who you really are and not who the bullies want you to be. Try reading the list out loud while looking in the mirror and smiling at yourself, this can really help boost your confidence in yourself.

I hope this helps and they stop bullying you soon but please talk to someone about it and don't let the bullies change you, be proud of who are you.

My 2001 f-250 won't run the fuel pump kicks on and continues to run removed the plugs on injectors one at a time and still does same thing could it be the computer

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

From start to end troubleshooting these problems I suggest you to check the help link below and follow its procedure: -----

After a full diagnostic, result said water pump needed to be replaced. They want $675.150 -pump,425-labor. I'm not a car chic,but somethings gotta be cheaper than that.C an i do this myself?

yes you can but its pretty deep inside the engine for most non mechanic people. if you feel confident doing a timing belt then the water pump is just one step away.
was the car overheating or leaking coolant or something? was curious how they got to that conclusion.

Breaker kicks off as soon as switch is turned on

the gfci is defective from moisture even after they dry they can be defective,access the cord inside the machine and try a different cord and see if this is your problem,otherwise the pump motor could be bad,the bypass valve on the pump could be bad,if you could run it you could check current draw with an amprobe,but not if it wont start

I have a whirlpool duet sport with an error code F21. It is not a blocked drian pipe, and is making a noise with the pump.

check drain trap for restriction
If the drain time exceeds 8 minutes, the water valves turn off.
This error code is only shown in Diagnostic test.
Possible Causes/Procedure
- Ask the customer how much detergent they are using and if it is HE
detergent. May have too much suds present causing this condition.
- Turn washer ON to verify pump operates; run the drain cycle.
- Check the drain hose and make sure it is not plugged or kinked.
- Unplug washer or disconnect power
- Make sure that wire harness connections at the Drain Pump, Pressure SW,
& CCU (DP2, PR6 cavities) connectors are not broken or with wires detached,
and that connector internal pins are visible.
- Check continuity from the Drain Pump & CCU (DP2 cavity) connectors.
- Check continuity from the Pressure SW & CCU (PR6 cavity) connectors.
- If the continuity diagnosis failed, Main Harness must be replaced.
- Make continuity test to the Pressure SW. See page 8.
- Check the resistance of the motor pump. See page 8.
- Plug in washer or reconnect power.
- Run the drain cycle.
- If the failure continues, unplug washer or disconnect power.
- Check the drain pump filter for foreign objects.
- Disassemble the drain pump from the washer.
- Check that the impeller is not detached from the motor shaft. If the
impeller is detached from the shaft, is broken or has any scratches,
the drain pump must be replaced.
- Plug in washer or reconnect power.
- Verify the unit operation by performing the Diagnostic Test cycle.
See page 5.
- After the diagnostic test has finished, unplug washer or disconnect
power and wait for 15 seconds.

Honda GC190 engine shuts down on my Karcher 3000 PSI PW

Well would you believe that I have the very same problem. I suspected that the pump was seizing up, so we tried the pump on another unit and it worked fine. On inspection of the motor we found the cam (which also operates the decompression mechanism) was worn out. It's made of hard plastic. It is only about 7 dollars too, so cheap enough to fix. I have mine ordered now and feel pretty confident that that should fix it.

Cranks fast but wont start

Hi, You did a good job of diagnosing your problem. Gas in bowl and dry plugs, starts with fluid, But, to quote you, "won't go through carb" . If you feel confident, you should disassemble and clean the carb, as that is going to be the problem. As a tip, if the genset is going to sit make sure to turn off the fuel flow to the engine and run till the engine dies. They do not like to sit any length of time with fuel in the carb. Good Luck, this should Fixya!

Cycle just continues with the pot symbol blinking

disconnect the hose and run it into a bucket, is it pumping freely?.

did you check the trap for a blockage?

You may have a leak in the pump housing area below the unit, this would cause the drain pump to run continually.
